In accordance with an embodiment of the present invention, the control panel 400 and the mounting part 110 at which the control panel 400 is mounted may be provided at a front side of the body 100 for a user to easily use the control panel 400. According to an exemplary embodiment of the present invention, the mounting part 110 may be formed at a front side of the paper discharge device 260.
[0035] The mounting part case 111 may be mounted, for example, below the control panel 400. The mounting part case 111 may forma portion of a front surface and a portion of a side surface of the mounting part 110. A card reader 500 configured to recognize a card may be disposed, for example, at a front side of an inside of the mounting part case 111, as illustrated on FIG. 3. Since the control panel 400 may be designed to be disposed at a height at which a user may easily use the control panel 400, the card reader 500 may be disposed at the mounting part 110 adjacent to the control panel 400, so a user may be able to have a card readily accessible to the card reader 500. Since the card reader 500 may be disposed at an inside of the mounting part case 111 that forms the mounting part 110, the card reader 500 may be disposed at a front side of the paper discharge device 260 in a similar manner as the mounting part 110.
[0036] The control panel 400, which is disposed at a front side of the body 100 as illustrated in an exemplary embodiment of the present disclosure, may be disposed at a height that is between, for example, 381mm and 1370mm, to facilitate a seated person, for example, a disabled person sitting in a wheelchair, to easily use the control panel 400. For the card reader 500 to also be easily used by a seated person, the card reader 500 may be also disposed at a height between about 381mm and 1370mm. The card reader 500 may be disposed at an inside of the mounting part case 110 at an upper side of which the control panel 400 is mounted, and thus the card reader 500 may be disposed at a position lower than the position of the control panel 400.
[0037] The mounting part case 111, as illustrated on FIG. 4, includes a supporting member 112 protruding from an inner surface of the mounting part case 111 to support a lower end of the card reader 500, and a pressing member 113 allowing the card reader 500 to come into contact with the inner surface of the mounting part case 111 by pressing the card reader 500 placed on the supporting member 112 toward the inner surface of the mounting part case 111.
[0038] For the installation of the pressing member 113, a pair of hinge holes 111a at which one end of the pressing member 113 is rotatably installed may be provided at one side surface of the inside the mounting part case 111 on top of one another. A locking protrusion 111b at which the other end of the pressing member 113 is supported in a locked state may be provided at the other side surface of the inside the mounting part case 111. In an exemplary embodiment of the present invention, a plurality of the locking protrusion 111b may be provided to correspond to varied thicknesses of the card reader 500 while being disposed in parallel to each other.
[0039] The pressing member 113 may be formed of elastically deformable material. The pressing member 113 may include at an end thereof a pair of hinge protrusions 113a rotatably installed at the pair of hinge holes 111a. At another end thereof the pressing member may include a locking part 113b locked with the locking protrusion 111b, and an elastic part 113c allowing the pressing member 113 to be elastically deformed.
[0040] According to an exemplary embodiment of the present invention, the pressing member 113 may be formed of a wire that is bent, for example, a U-shape. Thus, a U-shaped end portion of the wire forms the locking part 113b. Tips of the wire may be bent, for example, outwards or inwards to form the hinge protrusion 113a. A side portion of the wire may be bent in a spiral shape to form an elastic part 113c to generate elasticity.
[0041] When the locking part 113b of the pressing member 113 is separated from the locking protrusion 111b, the card reader 500 may be placed on the supporting member 112. By rotating the pressing member 113 as illustrated in FIG. 5 to an elastically deformed state such that the pressing member 113 is supported by the card reader 500 and the locking part 113b of the pressing member 113 is locked with the locking protrusion 111b, the card reader 500 maintains a state of contact with the inner surface of the mounting part case 111 due to the elastic restoration force of the pressing member 113.
[0042] Since the mounting part case 111 may be formed to have a significantly wide width and height compared to the card reader 500, and the card reader 500 may contact the mounting part case 111 with the pressing member 113 that is formed of the elastically deformable material, various types of card readers 500, each having, for example, a different width, height, and/or thickness may be installed inside the mounting part case 111.
[0043] In accordance with an exemplary embodiment of the present disclosure, the card reader 500 may be positioned at a front surface side of the body 100 and installed inside the mounting part case 111 positioned at a certain height allowing to facilitate accessibility by a user. But the present disclosure is not so limited, and may be installed, for example, at an inner side of a front surface or at an inner side of a side surface of the case 101, for example, that forms an external appearance of the body 100.
[0044] In accordance with an exemplary embodiment of the present disclosure, the card reader 500 may be supported by the inner surface of the mounting part case 111, but the present disclosure is not limited hereto. By forming a hole allowing the front surface of the card reader 500 to be exposed therethrough at the mounting part case 111 and by installing the front surface of the card reader 500 at the hole, the front surface of the card reader 500 may be disposed in a same plane with the front surface of the mounting part case 111.
[0045] The card reader may be provided with a lower end thereof being supported on the case or on the supporting member provided at an inner side of the mounting part case.
